The crests (bright) and troughs (dark) of waves spread out after they were produced. The picture applies to both light and sound waves. Titima Ongkantong

A new type of laser uses sound waves to help to detect weak forces

Most people are familiar with lasers. But what about a laser made with sound rather than light? A couple of physicists have now created one that they plan to use for measuring imperceivable forces.
A silica sphere with a radius of 50 nanometers is trapped levitating in a beam of light. J. Adam Fenster, University of Rochester

Experiments with optical tweezers race to test the laws of quantum mechanics

The discovery and development of optical tweezers won the 2018 Nobel Prize in physics. Now physicists are using this tool to crack some of the fundamental questions behind how the universe works.

We’ve designed a ‘flux capacitor’, but it won’t take us Back to the Future

Physicists have designed an electrical component that breaks time-reversal symmetry. Not quite the time machine from Hollywood but it should help with communication technology and quantum computing.
After this episode, you’ll be able to explain how quantum mechanics affects everything from the way your jeans are cut to the headphones you use. Cindy Zhi/The Conversation NY-BD-CC

Trust Me, I’m An Expert: The explainer episode

Today on Trust me, I'm An Expert, we're explaining the tricky topics: what is quantum mechanics? What does the research say about lone actor terrorism? And why do people like pimple popping videos?
An illustration of the two 20-micrometre-wide vibrating drumheads, each composed of trillions of atoms, in an entangled quantum state of motion. Petja Hyttinen and Olli Hanhirova, ARKH Architects Ltd.

Experiment shows Einstein’s quantum ‘spooky action’ approaches the human scale

We usually think of quantum entanglement in the realm of atomic systems, but now it’s been scaled up to relatively massive objects. This opens the door to new kinds of technology.
How fast can quantum computing get? Research shows there’s a limit. Vladvm/Shutterstock.com

Quantum speed limit may put brakes on quantum computers

A future that continues to have increasingly fast computing depends on quantum physics – but research is showing that there are limits to how fast quantum computers can go.

How quantum mechanics can change computing

As companies make quantum computers available through their cloud services, take a look at what it means for computing to move beyond classical mechanics and into quantum physics.
